db-wavelet
- Matlab环境下利用Daubechies小波族中的db10小波对散斑退化图像进行了压缩数值仿真研究。研究表明:阈值以及分解层次的选取影响着图像压缩的质量。-Matlab environment using Daubechies wavelet tribal db10 wavelet the withdrawal of speckle image compression for the numerical simulation. Research shows : the threshold le
adaptive-wavelet
- 本程序实现了自适应的选取小波基函数以实现图像疵点检测。
xbryz
- 此代码,可以完成matlab下的小波软阈值图像去噪,可以做不同阈值下的图像去噪,并通过峰值信噪比psnr的比对来说明阈值选取的方法-Wavelet threshold denoising compared soft threshold and hard threshold and the current method of calculating the various thresholds and thresholds approach the performance of function,
Face-recognition
- 本文针对人脸图像的特点,选取一组Gabor 小波核,并用这组Gabor 小波核对人脸图像进行Gabor 小波变换,提取人脸 图像的有效信息。在此基础上,用2DPCA 对Gabor 小波提取的 数据矩阵进行降维,最后用最近邻法对人脸进行分类。-In this paper, the characteristics of face images, select a set of Gabor wavelet kernel, and check with this set of Gabor wav
